I just bought and installed a Toto Drake CST744SG (C744EG bowl & ST743S tank), and was surprised to see it had a green fill valve in it instead of a blue one. From all the reading I've done on this forum, I was under the impression that the G-Max valves had a blue cover and the E-Max valves had a green cover. Both the tank markings and the label on the box list it as a ST743S which is the 1.6gpf G-Max tank for the Drake. Did the wrong fill valve get installed in the tank?
